That is the most irresponsible post I have read to date on this forum. You may be of the opinion that mixed tanks are difficult but that is simply not the case.
Wow, Jell, the most
irresponsible post? A little hyperbole, don't you think?
It's a well recognized fact that you keep a multi-species tank, and I pass no judgment on you because it's clear that you are observant and quick to make adjustments if territorial disputes and aggression become problematic to the health of the frogs.
However, proselytizing about the merits of mixing is another thing entirely. I consider mixing to be an advanced subject that shouldn't be approached by inexperienced novice keepers because there are many variables that could contribute to potentially devastating failure.
Your experiences should be shared so that others can read about them, research on their own and come to their own decisions and conclusions.
